Application filed November 16, 191.4. Serial No. 872,280.

To all 'whom it may concern:

Be it known that we, RICHARD F. BEUT- LIGH and FRANK SOCHUREK, J r., citizens of the United States, residing, respectively, at Chicago, in the county of Cook and State of Illinois, and West Allis, in the countyof Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Heaters, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

The main objects of this invention are to produce a light, compact portable heater,

freight cars to prevent freezing of their contents, and for other purposes; a heater which will keep a fire for a long time without replenishing with fuel and without attention; which will be economical and safe in operation; which can be easily charged with fuel and in which the fire can be easily stopped any time when the charge has been but partially consumed without dumping; and generally to improve the construction and operation of heaters of this class.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

In the accompanying drawing, a heater embodying the invention in its preferred form and construction is shown partly in elevation and partly in vertical medial section.

The heater, which may be conveniently constructed as shown, mainly of sheet metal, although other material may be used, comprises a magazine a, having a funnel-shaped lower portion b an inverted frustum-shaped iire pot c, surroundingand extending below the lower portion of the magazine and forming therewith the combustion chamber d; a conical grate e, seated normally in the fire pot c below the opening in the lower end of the magazine; and a radiator 7, surrounding the fire pot and forming therewith an annular heating chamber g.

The magazine a, is removably mounted on the radiator 7 and its funnel-shaped lower portion b, which forms a greater angle than the fire pot 0 to the vertical axis of the heater, is removably fitted into the upper end of the fire pot.

The top of the magazine is formed with Ymade of generally cylindrical form an opening for charging it with fuel, and is provided with a removable cover L, having a handle z'. The handle may be made as shown, of a piece of band metal, the ends of which project beyond the margin of the cover on opposite sides thereof and are adapted to be turned with the cover underneath keepers y' attached to the top for securely holding the cover in place. At or adj acent to the top on opposite sides thereof, the magazine is provided with snap hooks 70, or other means for suspending the heater from the roof or ceiling of a car.

The upper portion of the magazine, which is preferably of cylindrical form, is provided at its lower end next to the top of its funnel-shaped lower portion with a reinforcing metal band Z, riveted 0r otherwise fastened thereto and provided on opposite sides with handles fm, and at intervals around its circumference with lugs n.

The radiator f, which is also preferably corresponding in diameter with the upper part of the magazine, is provided at its upper end with a metal reinforcing band o, riveted or otherwise fastened thereto.

The bands Z and 0 are preferably of angle form or flanged, tc stiffen and strengthen them without unduly increasing their weight and to form extended bearing faces for each other. At intervals around its circumference the band 0 is provided with stirrups or pivoted loops Q9, adapted to be turned upwardly over the lugs 'n on the band Z, for detachably fastening the radiator f with the fire pot and grate supported thereby, to the magazine.

'Io prevent the detachment and separation of the radiator from the magazine and to bind and hold them tightly together, the stirrups or loops j? are provided with thumb screws g, for engagement with sockets in the upper sides of the lugs n.

The upper portion of the fire pot o above the grate and above the lower end of the magazine is perforated to allow the hot gases and products of combustion to pass from the combustion chamber CZ into the heating chamber g which surrounds it.

The grate e, which is normally seated and supported on an internal rib or shoulder r in the fire pot, has an imperforate central portion below the feed opening in the lower end of the magazine, and a perforated zone or belt adjacent to its periphery. A chain s, fastened to the center of the grate, passing upwardly therefrom through the magazine and suspended at its upper end on a hook t or otherwise adjustably connected with the top of the magazine, affords means for lift ing the grate and holding it against the magazine to close the feed opening in its lower end and cut ofl" the supply of fuel V'to the combustion chamber. Y

The ire pot c into which the funnelshaped lower portion of the magazine ts adjacent to i-ts upper end, removably lits into and is supported adjacent to the grate by a conical deflector u, riveted or otherwise fastened around its base to the radiator j".

The radiator f, which is preferably corrugated as shown, to increase its radiating surface, is formed adjacent to its upper end with outlet openings o, and adjacent tothe deflector u both above and below the same, with air inlet openings w and z.

A short distance below the lower open end of the lire pot c the radiator is provided with an imperforate bottom i, forming an ash receptacle. At its lower end the radiator is reinforced by a metal ring ror base z, which is riveted or otherwise fastened thereto, and is provided at suitable inter vals with legs or feet 2, upon which the heater may stand and by which itmay be secured to .a floor when it is not suspended from an overhead support, the legs or feet supporting the bottom of the heater above the floor and permitting air to circulate between them, thus avoiding danger of ire.

In ythe operation of the heater, the magazine a `and the grate e being removed from the fire pot o and ,radiator f, .a re is started with lindling placed inthe lower part of the fire pot on the bottom y. The magazine and grate arethen replaced in position and a small quantity of fuel such as charcoal, introduced through the opening in the top of the magazine, spreads over the perforated outer portion of the grate and is ignited from the fire below. After a fire has` been thus started on the grate the magazine is charged with a sufficientv quantity of Vfuel to maintain the fire for the desired length of time, especially if the heater is used for warming ,a car, and the fuel is automatically fed from the magazine to the grate and distributed thereon as required as long as the charge in ,the magazine lasts, or until the re is stopped by lifting the grate and cutting off the supply before it is exhausted. Air entering the base of the heater through the lower openings in the radiator, passes thence upwardly through the lower open end of the fire pot c, and through the .openings in the outer part of the grate, maintains combustion of the fuel thereon, the hot gases and `products of combustion `from the '.unconsumed combustible burning fuel inthe combustionV chamber (Z, escaping therefrom through the openings in the upper part of the fire pot cinto the heating chamber g, as indicated lby arrows. The gases escaping from the chamber Z through the openings in the fire pot, are-supplied with air through the openings w in the lowerfpartof theradiator above the defiector u, and are thus consumed, producing.additional heat, the products of combustion mingled with heated air escaping from the openings .e in the upper part of the radiator, .together with the heat radiating from the l'heated wall .of the radiator f, maintaining the desiredV temperature in ,the car, ora temperature abovefreezing.

At the end `of the run, or when there isno further occasion for Vthe heater, if there is -any-fuel left therein, the fire is stopped, and the unconsumed fuel is saved by lifting the grate e by means yof the chain s, thereby closing the opening in the lower end of the magazine and cutting off the ,supply of fuel to the .combustion chamber. ny ,ashes 4or refuse which have accumulated in the base ofthe heater `may be readily removed ,therefrom by unfastening and lifting the magazine `from the radiator and fire pot, the .grate being held by the chain s in place against'the magazine and closing the feed ,opening therein. When the magazine k.has been thus removed, the fire pot can be readily removed if desired froml the radiator, and the latter inverted to discharge any ashes or refuse kit may contain.

Vhen the parts of the heater `are `assembled and secured together and a fire has been kindled therein as above explained, it

requiresno further care or attention as long as the supply of fuel with which it is charged lasts; As no fire or ashes can escape from the heater while it is in operation and under `ordinary conditions, danger of injury to the car or its contents from fire or ashes, is avoided. j

arious changes in the .details of construction and arrangement of parts may be made without materially .affecting the operation `of the heater, and without departing from the principle of the invention as delined in the following claims.
